4) You didn't get me... switching shadowplay (on then off / blank screen
appears for second) in gfe enables nvfbc, disabling service completely
will disable nvfbc...
I use steam streaming with maybe 1% performance impact... streaming
service in task manager uses 1-3% of cpu...
Also using fast/balanced/beautiful impacts client performance together
with bandwidth limit settings auto/unlimited...
